Vaadin 8 & Maven & Proxy(?)

Hi,
In order to play a little bit with Vaadin 8 I've done the following.

Downloaded Eclipse Neon.2
Installed the Vaadin plugin.
Tried to create a Vaadin 8 project...
The last part didn't go as planned, I get the following exception:

Could not resolve archetype com.vaadin:vaadin-archetype-application:8.0.0 from any of the configured repositories.
Could not resolve artifact com.vaadin:vaadin-archetype-application:pom:8.0.0
Failure to transfer com.vaadin:vaadin-archetype-application:pom:8.0.0 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact com.vaadin:vaadin-archetype-application:pom:8.0.0 from/to central (https://repo.maven.apache.org/maven2): Unrecognized SSL message, plaintext connection?

Same thing happens when I try to create a Vaadin 7 (maven) project.
I have setup the proxy at the settings.xml C:\Users\x\.m2\settings.xml
but nothing has changed. My settings .xml file is below:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies>
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>iproxy</host>
      <port>80</port>
      <username></username>
      <password></password>
      <nonProxyHosts>localhost,127.0.0.1</nonProxyHosts>
    </proxy>
  </proxies>
  <profiles></profiles>
  <activeProfiles/>
</settings>

Any ideas??!??!
